Color Doppler ultrasound was used to image the ureteral jets in 17 healthy subjects and 26 patients with ureteral calculi proved with intravenous urography. In patients with ureteral calculi, three patterns of ureteral jets were seen: no detectable urine flow from the symptomatic side (12 patients), low-level continuous flow from the symptomatic side (four patients), and periodic ureteral jets on the symptomatic side that were not significantly different from ureteral jets of healthy subjects (10 patients). Of the 12 patients with high-grade obstruction on urograms, 11 had ureteral jets significantly different from those of healthy subjects (either no detectable ureteral jets or continuous low-level jets on the symptomatic side). Only three of the 11 patients with low-grade obstruction or nonobstructing stones had ureteral jets that were different from those of healthy subjects. It is concluded that analysis of ureteral jets with color Doppler can enable detection and qualitative determination of the degree of ureteral obstruction in many patients with unilateral ureteral calculi.
采用彩色多普勒超声对17名健康受试者以及26名经静脉肾盂造影证实患有输尿管结石的患者的输尿管喷尿情况进行成像。在输尿管结石患者中，观察到三种输尿管喷尿模式：患侧无明显尿流（12例患者）、患侧低水平持续尿流（4例患者）以及患侧周期性输尿管喷尿，且与健康受试者的输尿管喷尿无显著差异（10例患者）。在静脉肾盂造影显示为重度梗阻的12例患者中，11例患者的输尿管喷尿与健康受试者明显不同（患侧无明显输尿管喷尿或持续低水平喷尿）。在11例轻度梗阻或无梗阻结石患者中，只有3例患者的输尿管喷尿与健康受试者不同。结论是，彩色多普勒分析输尿管喷尿能够在许多单侧输尿管结石患者中检测并定性判断输尿管梗阻的程度。
